摘要:
In an internal combustion engine, at least one of the pressure and temperature in an intake passage downstream of a throttle valve is calculated using an expression of a relationship established based on the law of conservation of mass among an amount of air passing the throttle valve and flowing into the intake passage, an amount of exhaust gas passing an exhaust gas flow control valve and flowing into the intake passage, and an amount of gas flowing from the intake passage into a cylinder of the engine, and an expression of a relationship established based on the law of conservation of energy among an amount of energy of the air passing the throttle valve and flowing into the intake passage, an amount of energy of the exhaust gas passing the exhaust gas flow control valve and flowing into the intake passage, and an amount of energy of the gas flowing from the intake passage into the cylinder of the engine.

Provided is a belt-drive continuously variable transmission which comprises a pair of drive pulley and driven pulley, and a belt engaged with the pulleys. The belt includes an endless carrier and a plurality of transverse elements closely arranged on the carrier. Each transverse element has an edge and rotatable about the edge in the longitudinal direction of the belt and converging side faces for contact with contact surfaces of the pulleys. Each of the side faces is curved toward each of the contact surfaces in such a manner as to have, when each of the transverse elements is observed in a plan view, such a circular arc that is of a predetermined radius R and has a center located on a straight line perpendicular to each of the contact surfaces and extending through a point at which the edge and each of the contact surfaces meet.

An image recording apparatus includes a plurality of print engine aligned in a advance direction in which a transporting member transports a recording medium. A first one of the plurality of image-forming sections records a first detection pattern on the transporting member and a second one of the plurality of image-forming sections records a second detection pattern on the first detection pattern. A color shift detecting section detects the amount of color shift between the first and second ones of the print engines by measuring an intensity of light reflected by the first and second detection patterns. Based on the amount of color shift, a correcting section corrects a position of the image recorded on the recording medium. The detection pattern may be of different configurations, depending on the direction in which color shift occurs, i.e., traverse, advance, and oblique directions. The detection pattern includes a plurality of blocks aligned in a row, each of the plurality of blocks having at least one stripe.

A clutch is provided with a drive-side rotational body and a driven-side rotational body, which can move in the axial direction between a coupled position and a decoupled position. The driven-side rotational body has a groove having a helical portion and an annular portion that is deeper than the helical portion. The driven-side rotational body is urged toward the coupled position by an urging member. The driven-side rotational body is moved to the decoupled position against the urging force of the urging member by insertion of a pin into the helical portion. A projection is provided on the tip of the pin, and a recessed groove for accommodating the projection when the pin is inserted into the helical portion is provided in the bottom surface of the helical portion.

A power transmission unit for a vehicle including a first clutch device that selectively allows a torque transmitting route from an input shaft to an output shaft via a first gear train to transmit torque therethrough, a dog clutch that switches the torque transmitting route from the input shaft to the output shaft between a continuously variable speed change route in which the torque is transmitted through a continuously variable transmission and a reverse route in which the torque is transmitted through a second gear train, and a second clutch device that connects and disconnects both of the continuously variable speed change route and the reverse route to/from at least any one of the input shaft and the output shaft.

A disc brake pad assembly includes a pair of locking bent portions formed at circumferential end portions of an inner shim plate by being bent towards an opposite side to a pressure plate. Locking through holes are formed individually at base end portions of the locking bent portions. A pair of locking projecting pieces are individually formed so as to project circumferentially from an outer main body portion included in an outer shim plate. A distance between distal edges of the locking projecting pieces is larger than a space between the locking bent portions, and a circumferential length defined between radial side portions of the locking projecting pieces is shorter than the space. The inner main body portion and the outer main body portion are superposed on each other in a state that the locking projecting pieces are brought into engagement with the locking through holes.

The clutch is provided with a drive-side rotational body, a driven-side rotational body, driven-side rotational body, and an urging member. The driven-side rotational body is movable in the axial direction of the drive-side rotational body between a first position, at which the driven-side rotational body is coupled to the drive-side rotational body, and a second position, at which the driven-side rotational body is decoupled from the drive-side rotational body. The urging member urges the driven-side rotational body from the second position toward the first position. The driven-side rotational body includes a helical groove that extends in the urging direction of the urging member. The clutch is further provided with a pin that can be inserted into the helical groove.

A clutch is provided with a drive-side rotational body and a driven-side rotational body, which is movable in the axial direction of the drive-side rotational body between a coupled position. The driven-side rotational body has a groove having a helical portion and an annular portion. The clutch also includes an urging member and a pin that is selectively inserted into and retracted from the groove. The clutch moves the driven-side rotational body to the decoupled position against the urging force of the urging member by inserting the pin in the helical portion. The clutch further includes a restricting portion that restricts shifting of the position of the pin from the annular portion to the helical portion when the pin is positioned in the annular portion.

A radio (102) in a sensor network and powered by electricity includes a data communicating unit (114) performing data communication; and a pulse interval demodulating unit (111) configured to (i) detect, from a signal (11c) with signals for corresponding frequency channels overlapped, a frequency channel indicated by a time interval between two pulses in a wake-up signal (1R) included in one of the frequency channels and (ii) cause the data communicating unit (114) to perform the data communication over the detected frequency channel.
摘要:
A power transmission unit including a first clutch device that selectively enables and disables a torque transmitting route from an input shaft to an output shaft via a first gear train to transmit torque therethrough, a dog clutch that switches the torque transmitting route from the input shaft to the output shaft between a continuously variable speed change route in which torque is transmitted through a continuously variable transmission and a reverse route in which torque is transmitted through a second gear train, and a second clutch device that selectively enables and disables both of the continuously variable speed change route and the reverse route to transmit torque to the input shaft or the output shaft. The first clutch device and the second clutch device are separately disposed on any of the input shaft and the output shaft in a manner to be situated at different axial positions.
